Product Feature

With the smooth surface, thermal storage ball owns the characters of high mechanical strength, high abrasion resistance, high thermal conductivity & thermal capacity, high thermal stability, and excellent heat endurance.There are three types, including ceramic ball, porous ceramic column and porous ceramic ball. It's specially applied as thermal storage packing in heat accumulator of air separation equipments, heating stove of blast furnace gas in the steel industry. During the process of steel rolling, if thermal storage ball is installed, it can preheat both air and gas so as to ensure burning temperature achieve the requirement quickly required by heating of billet during steel rolling.

Application

As grinding media, this product is widely used in Ceramic industry, cement industry, paint industry, Color industry, chemical industry, pharmaceutical industry, coating industry and mining industry
